Abstract

The Vlasov-Maxwell equations are used to investigate properties of the electron-ion two-stream instability for a continuous, high-intensity ion beam propagating in the z-direction with directed axial velocity V _b=β_bC through a background population of (stationary) electrons. The analysis is carried out for arbitrary beam intensity, consistent with transverse confinement of the beam particles, and arbitrary fractional charge neutralization. Stability properties are calculated for dipole perturbations with azimuthal mode number l=1 about monoenergetic ion and electron distribution functions
